NVDA fails to delete temporary files with .delete extension

[paulber19]

After a faulty installation of an add-on, a temporary file with the .delete extension remains in the "addons" folder and NVDA reports an error in the log on each restart.
ERROR - addonHandler.removeFailedDeletion (17:59:45.736) - MainThread (3760):
Failed to delete path E:\documents\Paulo\temp\nvda 2024.4\userConfig\addons\tmpneiy66px.delete, try removing manually

Steps to reproduce:

Actual behavior:

• choose an add-on in the addons folder
• open a file of this add-on in text editor
• update this add-on and restart NVDA
• nvda reports an error loading the add-on
• close the text editor and restart NVDA
• the add-on is correctly installed but an error is reported in the log.

Expected behavior:

Since it is possible to manually delete this fileNVDA should be able to do that too à when it starts.
